![]() ![]() ![]() This is typically known as LLDP-MED.Ĭonfiguration of LLDP is really simple, depending on your switch and IOS version it might be enabled or disabled by default. To accomplish this, an enhancement was made which is called MED (Media Endpoint Discovery). Some network end devices (like IP Phones) can use LLDP for VLAN assignment or PoE (Power over Ethernet) requirements. Devices that support LLDP use TLVs to send and receive information to their directly connected neighbors. These are called TLVs (Type, Length, Value). ![]() LLDP uses attributes that contain a type, length and value descriptions. This allows non-Cisco devices to advertise information about themselves to our network devices. The big difference between the two is that LLDP is a standard while CDP is a Cisco proprietary protocol.Ĭisco devices support the IEEE 802.1ab version of LLDP. LLDP is a layer two discovery protocol, similar to Cisco’s CDP.
